CAST supports Azure Cosmos DB via its com.castsoftware.nodejs extension. Details about how this support is provided for Node.js source code is discussed below.
Objects
| Icon | Description |
|---|---|
| Node.js Azure CosmosDB Database |
| Node.js Azure CosmosDB Collection |
| Node.js Azure CosmosDB Unknown Database |
| Node.js CosmosDB Unknown Collection |
Detailed support
The @azure/cosmos package is supported. Whenever a container client use one of the method listed in the following table, a link is created to the corresponding collection.
| LinkType | Methods from Container | Methods from Item | Methods from Items |
|---|---|---|---|
| useDelete | delete | delete | batch, bulk |
| useSelect | - | read, query | batch, bulk, query, readAll |
| useUpdate | - | replace | batch, bulk, upsert |
| useInsert | - | - | batch, bulk, create |
If the evaluation of the container name fails (either due to missing information in the source code or to limitations in the evaluation) a link is created to an Unknown collection.
What results can you expect?
When analyzing the following source code:
const CosmosClient = require("@azure/cosmos");
const client = new CosmosClient({ endpoint: endpoint, auth: { masterKey } });
const databaseId = 'My database'
const collectionId = 'My collection'
// CREATE DATABASE
const dbResponse = client.databases.createIfNotExists({
id: databaseId
});
database = dbResponse.database;
// CREATE COLLECTION
const coResponse = database.containers.createIfNotExists({
id: collectionId
});
container = coResponse.container;
// QUERY
var param = {
query: "SELECT * FROM root r WHERE r.completed=@completed",
parameters: [
{
name: '@completed',
value: false
}
]
};
const { result: results } = container.items
.query(param)
.toArray();
client.database(databaseId).delete()
you will get the following result:
Known Limitations
- The link type for bulk and batch methods is not evaluated. All possible link types are created.
